Assessments and Appeals

The Municipal Property Assessment Corporation (MPAC) assesses and classifies properties according to their use. They provide these values to the City of Cornwall on an annual assessment roll. To set your property's value, MPAC reviews recent sales of properties nearby. This ensures that properties with similar features have similar assessed values. When assessing a property, MPAC considers features that affect its market value including its: 

• Location (being on a corner lot or close to a park, golf course or railway)
• Lot dimensions
• Living area
• Age of the structure(s)
• Any major renovations or additions
• Quality of construction

The number of bathrooms, fireplaces, finished basements, garages and pools can also affect your property's value.
